System for displaying image

Abstract

A system for displaying images has a backlight module. The backlight module includes a light-guide, a frame and a lighting element. The frame holds the light-guide and has a first elastic element. The lighting element is held within the frame and has a first side and a second side opposite to each other. The first side touches the first elastic element of the frame. The second side touches the light-guide.

1 . An image-displaying system with a backlight module, the backlight module comprising:
 a light-guide;   a frame body, which holds the light-guide and has a first elastic element; and   a lighting element, which is held in the frame body and has a first side and a second side that are opposite to each other, wherein the first side touches the first elastic element of the frame body, and the second side touches the light-guide.   
     
     
         2 . The image-displaying system of  claim 1 , wherein the first elastic element pushes the first side of the lighting element so that the second side of the lighting element presses firmly against the light-guide. 
     
     
         3 . The image-displaying system of  claim 1 , wherein the second side of the lighting element aligns with the light-guide. 
     
     
         4 . The image-displaying system of  claim 1 , wherein the first elastic element is a rib. 
     
     
         5 . The image-displaying system of  claim 4 , wherein the central portion of the first elastic element has an arc. 
     
     
         6 . The image-displaying system of  claim 4 , wherein the first elastic element has a profile designed according to a profile of the first side of the lighting element. 
     
     
         7 . The image-displaying system of  claim 1 , wherein the first elastic element is a suspension arm. 
     
     
         8 . The image-displaying system of  claim 7 , wherein the first elastic element has a cylindrical tail. 
     
     
         9 . The image-displaying system of  claim 1 , wherein the frame body has a cavity, and the first elastic element is formed adjacent to the cavity. 
     
     
         10 . The image-displaying system of  claim 1 , wherein the frame body further comprises a second elastic element for pushing the light-guide toward the lighting element and to touch tightly against the frame body. 
     
     
         11 . The image-displaying system of  claim 10 , wherein the second elastic element is a suspension arm. 
     
     
         12 . The image-displaying system of  claim 10 , wherein the second elastic element has a cylindrical tail. 
     
     
         13 . The image-displaying system of  claim 10 , wherein the frame body has a cavity, and the second elastic element is formed adjacent to the cavity. 
     
     
         14 . The image-displaying system of  claim 1 , wherein the lighting element is disposed at one corner of the frame body. 
     
     
         15 . The image-displaying system of  claim 1 , wherein the lighting element is disposed on an inner edge of the frame body. 
     
     
         16 . The image-displaying system of  claim 1 , wherein the lighting element is light emitting diode (LED). 
     
     
         17 . The image-displaying system of  claim 1  further comprising:
 a liquid crystal display (LCD) device having the backlight module and a liquid crystal display (LCD) panel, wherein the backlight module outputs a beam of light to the LCD panel for the LCD panel to display images.   
     
     
         18 . The image-displaying system of  claim 1  further comprising:
 an electronic device having the backlight module, a liquid crystal display (LCD) panel and an input unit, wherein the backlight module outputs a beam of light to the LCD panel, and the input unit couples to the LCD panel and provides an input to the LCD panel for the LCD panel to display images.   
     
     
         19 . The image-displaying system of  claim 18 , wherein the electronic device is a mobile phone, a digital camera, a personal digital assistant, a laptop computer, a desktop computer, a television, a vehicle display or a portable DVD player.
